Kubernetes is designed primarily for managing containerized workloads, but it can also support legacy virtual machine (VM) workloads through specific add-ons. Let’s analyze each option:

A. ADOT

Incorrect: The AWS Distro for OpenTelemetry (ADOT) is a tool for collecting and exporting telemetry data (metrics, logs, traces). It is unrelated to running VMs in Kubernetes.

B. Canal

Incorrect: Canal is a networking solution that combines Flannel and Calico to provide overlay networking and network policy enforcement in Kubernetes. It does not support VM workloads.

C. KubeVirt

Correct: KubeVirt is a Kubernetes add-on that enables the management of virtual machines alongside containers in a Kubernetes cluster. It allows organizations to run legacy VM workloads while leveraging Kubernetes for orchestration.

D. Romana

Incorrect: Romana is a network policy engine for Kubernetes that provides security and segmentation. It does not support VM workloads.

Why KubeVirt?

VM Support in Kubernetes: KubeVirt extends Kubernetes to manage both containers and VMs, enabling organizations to transition legacy workloads to a Kubernetes environment.

Unified Orchestration: By integrating VMs into Kubernetes, KubeVirt simplifies the management of hybrid workloads.

JNCIA Cloud References:

The JNCIA-Cloud certification covers Kubernetes extensions like KubeVirt as part of its curriculum on cloud-native architectures. Understanding how to integrate legacy workloads into Kubernetes is essential for modernizing IT infrastructure.

For example, Juniper Contrail integrates with Kubernetes and KubeVirt to provide networking and security for hybrid workloads.
